Wilmington Police and ATF officers arrested Erik Rudolph Arnebold after an investigation into drugs turned up 24 explosive devices.
Detectives say 23 of them were hidden down in a trap door under the house at 4705 Patrick Ave. in Wilmington.

The FBI on Friday confirmed that Istvan A. Merchenthaler, 42, was in custody. He faces charges in connection with a Ponzi scheme that officials say defrauded $2 million from investors over seven years, according to media reports in Pennsylvania.
